Double trouble: Rita Ora proved her love of sportswear extended beyond Adidas on Tuesday night, as she touched down in New York in a pair of trainers by rival Nike

The RIP crooner kept things casually cool for her long flight in the classic black Adidas tracksuit, complete with the iconic white stripes down the side.

Never without a hint of glamour despite her sporty sense of style, the blonde also carried a lavish Louis Vuitton handbag and swept her straight locks back with retro rectangular shades, as she landed in the Big Apple.

More notable however was her choice of footwear, which saw her sport a pair of shimmering gold Air Max 97 OG trainers by Nike, worth 0.

She just did it! More notable however was her choice of footwear, a pair of shimmering gold Air Max 97 OG trainers by Nike - despite being an Adidas designer and ambassador

The choice is a somewhat surprising one for the British beauty, who has been an Adidas designer and ambassador for three years.

Back in 2014, Rita signed her.4million contract with Adidas - with a source revealing at the time that she had 'been talking about designing for a number of years.'

The star has since gone on to design a huge fifteen collections for the brand, involving both clothing and footwear. MailOnline has contacted representatives of Rita and Adidas for comment.

Meanwhile the singer arrived back in the States after jetting to London to record her part on Simon Cowell's new charity single, in aid of the victims of the Grenfell Tower blaze.

Last week, a fire swept through the 27-storey tower block in just 15 minutes reportedly after a faulty fridge exploded - and it is now referred to as one of the worst in British history amid fears nobody on its top three floors survived.

Rita has always been proud of her London roots, growing up around Earls Court, before later moving to Kensal Rise - a stone's throw away from White City, where the blaze took place.

In order to raise money for victims, music mogul Syco thus enlisted Rita, alongside the likes of Louis Tomlinson, Leona Lewis, Craig David and Paloma Faith, to record a rendition of Simon and Garfunkel's hit Bridge Over Troubled Water.

After the charitable rita ora for adidas trip however, Rita is no doubt heading back to the States to continue work on her new solo album.

She released Your Song, her first track in two years, last month - and unveiled the saucy accompanying music video, which saw her clad in a top formed of two belts, the following week.
